    Glossary Topical JAK Inhibitors

    medications applied to skin to block Janus kinase enzymes

    Topical JAK Inhibitors, also known as Topical Janus Kinase Inhibitors or Topical JAKis, are medications applied directly to the skin to block the activity of Janus kinase enzymes. These enzymes play a role in the immune response and inflammation. By inhibiting them, these treatments can help manage conditions like alopecia areata, an autoimmune disorder that causes hair loss, by reducing inflammation and potentially promoting hair regrowth.
